In a typical scenario, EasyMorph updates unformatted (raw) data sheets in a spreadsheet, and the formatted sheets (with or without charts and pivot tables) reference data from the unformatted sheets.
Another option would be to run an Excel macro using the ‘Excel command’ action to add formatting to sheets. But that may not work on EasyMorph Server as VBA automations are not well suited for execution from Windows services.
